About the GSX-R125

The Suzuki GSX-R line has defined sportbike performance for over 30 years, with more than a million sold worldwide. So the dedicated Suzuki engineers who have devoted their lives to the GSX-R take their responsibilities very seriously. Meet the revolutionary Suzuki GSX-R125, with the best power-to-weight ratio and acceleration in the 125cc class. There is a science to building high-performance engines and the GSX-R125's DOHC engine is a perfect example of how to make a lot of power out of a very efficient and compact power plant. This power combines with strong torque and exceptional fuel economy, to create an engine worthy of the GSX-R marque.  At 134kg ready to ride, the GSX-R125 is light and compact, giving ultimate control in the corners for a fun and sporty ride. Low weight is key, this helps deliver a bike with responsive and rewarding handling for added confidence on the street and low lap times on the track. Contributing to the bikes low weight are the 10 spoke cast aluminium wheels. Having light weight wheels helps ensure great handling, for a ride that's fun and a machine that goes exactly where you want it to. The slim design of the spokes also adds to this GSX-R's great sportsbike looks, along with the sporty petal type brake discs front and rear. To make the best use of every ounce of power from the GSX-R125's class leading engine, the bikes sporty bodywork is also extremely aerodynamically efficient to reduce drag and maximise efficient speed. This design is the result of extensive wind tunnel development, and the sleek bodywork also enhances the GSX-R125's easy handling character. Furthermore, it also has the smallest projected frontal area in the 125cc class helping to achieve that best in class acceleration and supports high levels of fuel efficiency.
